Yoga Sutra 2.1

Taph Svadhyahyesvara Pranidhanani Kriya Yogah.

Accepting pain into your life and learning from it, instead of avoiding it for: purification, spiritual awareness (from the heart rather than ego), and surrender (dedicate everything) to the Divine. All of this makes up Kriya Yoga which is a deep energetic work or action (creation of tapas or fire/heat) of yoga in practice.

Yoga Sutra 2.1

Boredom is often the result of unfinished dreams. Keep dreams within tapas, with hot awareness (and self discipline). Everyone starts something, but few finish and continue to the end.
